摘要
地虎铜多金属矿位于从江地虎—翁浪—摆容韧性剪切带上,赋矿地层为下江群甲路组地层,围岩蚀变强烈,蚀变类型主要为硅化和绿泥石化,其次为绢云母化、黄铁矿化、黄铜矿化等,主要金属矿物有黄铜矿、黄铁矿、磁铁矿、方铅矿、闪锌矿,非金属矿物主要有石英、绿泥石、绢云母,矿石矿物主要在热液成矿期的石英—多金属硫化物阶段生成,矿体形态受该剪切带及其之上的次级褶皱联合控制,蚀变体控制着含矿带和含矿体的产出。
Dihu Cu-polymetallic deposit locates on the Dihu-Wenglang-Bairong ductile shear zone and is hosted by Jialu formation of Xiajiang Group.Wall rock alteration is characterized by widespread silicification,chloritization sericitization,pyritization and chalcopyritization.Ore minerals include mainly chalcopyrite,pyrite,magnetite,galena,sphalerite.Gangue minerals include mainly quartz,chlorite,seritite.Ore minerals are formed in hydrothermal mineralization period,quartz-polymetallic sulfide stage.Ore bodies are controlled by Dihu-Bairong ductile shear zone and secondary folds.Ore zones and ore bodies are controlled by alteration zones.
